As shown below, HQ and Branch Office are connected with each other through IPsec VPN tunnel. In HQ, there are TP-Link EAP controller, EAP1 and TL-ER6120 (VPN Router) in subnet 192.168.1.0/24. In branch office, there are TP-Link EAP discover utility, EAP2 and TL-ER6120 (VPN router) in subnet 192.168.0.0/24.

This document will introduce how to manage EAPs at different sites across Internet using TP-Link EAP/Omada controller (via VPN Tunnel with EAP discover utility). About how to choose VPN Router and set up site to site IPSec VPN tunnel, please refer to: Setting up Site-to-Site IPsec VPN on TP-Link Router

Step2. VPN settings on TL-ER6120 in HQ are similar with “Step 1”. Here we don’t describe them in detail any more. After all settings, the VPN tunnel will be established between HQ and Branch Office shown as below.

Step3. Configurations on PC that is running EAP Discover Utility in Branch Office

Run EAP discover utility, and fill in EAP/Omada controller’s IP address (192.168.1.253) and the Username/Password of the EAP (admin/admin by default). At last, click “Apply”.

Note: After EAP successfully adopted by EAP/Omada Controller, you don’t need EAP Discover Utility any more, thus you can remove the PC which is running the EAP discover utility from the network.

Step4. Run EAP Controller. The EAP will appear in EAP/Omada controller’s “pending” list, which means you can use EAP/Omada controller to adopt and manage this EAP now shown as below.
